Yakakwira-Tembiricha Steam Yekuyedza Gwaro reVortex Flowmeters
Kupisa kwepamusoro-soro kunopfuura 300°C kunogona kukuvadza zviri nyore vortex flowmeters kana kukonzera kukundikana kwengozi kana ikaedzwa zvisina kunaka. Iri gwaro rekuchengetedza rinobatsira kudzivirira zvikanganiso zve data, kupisa kwemidziyo, uye njodzi dzekuchengetedza.
1. Pre-Test Kuchengetedza & Kugadzirira
Usati waedza, dzikisa kudzvanywa kwepombi uye tembiricha kusvika kumazinga akachengeteka, uye pfeka magirovhosi asingadzivirire uye nhovo yechiso.
Murau wakakosha wekudzivirira: USAbvisa pombi yekuvharisa, asi chengeta inokwana hafu yetsvimbo yekuwedzera sensor yakafumurwa kuti itonhodze. Kuvharira transmitter mu insulation kunopisa nekuparadza zvemagetsi.
2. Installation & Straight Pipe Zvinodiwa
Kuyerera kusina kugadzikana kubva kumagokora kana mavharuvhu kunokonzera kukanganisa kwakanyanya kwechiratidzo.
- Upstream yakatwasuka pombi:15D–20D(pamusoro pe40D kana mavharuvhu ekudzora ari pedyo)
- Pombi yakananga pasi:≥5DKuverenga kusinganzwisisike kunowanzobva mukuiswa kwakashata, kwete mita yacho pachayo.
3. Parameter Setting: Saturated vs. Superheated Steam
Kusanganisa mhando dze steam ndicho chikonzero chikuru che data risingaite.
- Superheated steam: Inoda zvose zviri zviviri tembiricha uye kumanikidzwa muripo.
- Saturated steam: Inoda kanenge kamwe chete muripo weparameter.Kuvharira kusina kunaka kunogona kushandura chiutsi chakazara kuti chiite chipfunga chemvura, zvichitungamirira kumigumisiro isina kunyatsojeka kana isina kugadziriswa. Ita shuwa chaiyo RTD uye yekumanikidza transmitter kuiswa.
4. Signal Testing: Tarisa Waveforms, Kwete Kungoverenga
Shandisa oscilloscope kutarisa masaini akachena epulse. Ruzha rwakanyanya kazhinji runobva pakudengenyeka kwepombi. Isa zvikwiriso zvisingaite vibration nemapadhi kuti uderedze kukanganiswa.
